Engine Break-In
No single action on your part is as important to long, trouble-free
machine life as proper break-in of a new or rebuilt engine. Premix the
first tank of fuel with one pint of Polaris injection oil for each five gal-
lons of fuel. This, in addition to the lubrication supplied by the injection
system, will assure proper engine break-in.
Excessive heat build-up during the first three hours of operation will damage
close-fitted engine parts. Do not operate at full throttle or high speeds for
extended periods during the first three hours of use. Vary the throttle open-
ings and machine speeds to reduce friction on all close-fitting machined
parts, allowing them to break in slowly without damage.
Use of any lubricants other than those recommended by Polaris may cause
serious engine damage. We recommend the use of Polaris lubricants for your
vehicle.
Drive with extra caution during the break-in period. Perform regular checks
on fluid levels, lines, and all other important areas of the machine.
